Please note that we do no longer accept checks for payments for conference and sponsor fees. European banks, including our own banks, more and more discontinue to allow checks, which makes it more and more difficult for us to accept this kind of payment. We do accept Visa, Mastercard, American Express and bank wire.

We have discontinued our Twitter (now X) account by the end of September 2023. Our social media focus will continue to be on LinkedIn. Please connect with us there.

As of January 1, 2023, we no longer sell books from past conferences. Slides from most events after 2010 are available for sale in pdf format. Please contact us for details.
